Answer:
The correct option is C:
C) The representative sample contained more girls than boys.
Step-by-step explanation:
It is given that a random sample is chosen from a total students of 160 students. The sample can be of 10,15 or any small numbers of students as compared to 160. However, a sample cannot be of 160 students as it is defined as a population in this case.
A random sample is always unbiased. Which means that the sample chosen should have around the same proportion of girls to boys as it is in the population of 160.
We know that:
Total boys in 160 = 65
Total girls in 160 = 95
Proportion of girls to boys = 95/65 = 1.462
Which means that for every 1 boy, there are 1.462 of girls.
The same ratio is held in a random sample, hence the total number of girls will be greater than boys
Answer: The maximal margin of error is 4.822.
Step-by-step explanation:
Since we have given that
Number of bags = 38
Sample mean = 78 ounces
Standard deviation = 14.5 ounces
At 96% confidence interval for the true population mean bags of nut weight.
So, z = 2.05
As we know that formula for "Margin of error":
Hence, the maximal margin of error is 4.822.
You have a good day and good luck on that question
